Push notification IOS expo SDK upgrade from 48 to 50 Problems with App store builld

I am getting a push notification on actual device that is a development build and push notifications are working fine both when sending and receiving and using expo push notification tool. But, when I submit the app to the app store and test on testflight, No expo token is generated. It was working fine with expo sdk 48 but I recently upgraded to sdk 50 and now the token is not being generated.

 let token; let projectId; if (Platform.OS === "android") {   await Notifications.setNotificationChannelAsync("default", {     name: "default",     importance: Notifications.AndroidImportance.MAX,     vibrationPattern: [0, 250, 250, 250],     lightColor: "#FF231F7C",   }); } if (Device.isDevice) {   const { status: existingStatus } =     await Notifications.getPermissionsAsync();   let finalStatus = existingStatus;   if (existingStatus !== "granted") {     const { status } = await Notifications.requestPermissionsAsync();     finalStatus = status;   }   if (finalStatus !== "granted") {     alert("Failed to get push token for push notification!");     return;   }   projectId = Constants.expoConfig.extra.eas.projectId;   token = (     await Notifications.getExpoPushTokenAsync({       projectId: projectId,     })   ).data;   console.warn("projectId", projectId);   console.log("token", token);   console.log("projectId", projectId); } else {   alert("Must use physical device for Push Notifications"); } return token;} ````. Does anyone know what the problem can be?
